A Correct answer
Explanation

The 'a' (append) mode opens a file for writing only, places the pointer at the end, and creates the file if it doesn't exist. Option C (W+) would open for reading AND writing but would truncate the file. Options B (W) and D (A+) are incorrect for 'writing only' requirement.
